The cbmlink software should copy files and disks via the C2N232 cable on
Mac OS X.  Older Macs could be supported as well (I think the RS-422 can
be wired as RS-232 without added components), but someone else would have
to develop the serial routines.  The code is already rather modular, as it
supports AmigaOS, Win32 and POSIX.

A few weeks ago, I soldered a serial bus cable to the C2N232 and wrote some
more firmware.  It already successfully echoes the data from the serial bus
to the serial line, but the other way doesn't work yet.  Wolfgang Moser
suggested to make a new version of VC1541 that would speak to the C2N232,
and Torsten Paul (the author of VC1541) contacted me yesterday about that.
In that way, you could have a 1541 emulator running on virtually any system
that supports RS-232 at 38,400 bps and the C programming language.

Of course, you could also have a Star Commander style tool for copying disks,
but it may be difficult to reuse any code of Star Commander, as it has been
developed with MS-DOS specific tools.

If I'm making another run of the C2N232, I'll add some holes where the serial
bus cable can be soldered.  Also, I might make another version of the firmware
that allows you to plug the serial bus cable into the tape connector.
